MACHINE UNPACKING AND INSTALLATION

UNLOADING:

Remove the shrink-wrap covering the machine, carefully as not to damage painted

surfaces, electrical or hydraulic parts. Carefully inspect the machine for physical damage. If

damage is noted, notify the truck line at once. They may require inspection, and that a claim be

filed. Check that all standard accessories are with the machine. Some accessories may be boxed or

placed behind access doors or chip drawer. (See figure 2 & 3) The band saws are provided with lifting

eyes that screw into the top of the machine. These lifting eyes may be located in any of the

compartments shown by arrows in figure 1 & 2 above. Particular care should be taken in selecting

areas of the machine for handling, as electrical components and adjustment knobs can be marked up

or damaged. WARNING: Machine table may NOT

be used as a lifting point. Damage to the saw

and alignment problems could result. Remove the mounting bolt nuts from the machine. Using the

lifting eyes, remove the machine from the skid and put in place. (See figure 1)

INSTALLATION:

Location of the machine should take into consideration the ability to traverse

large work pieces. The machine is provided with holes in the base to anchor the unit to the floor.

Shims should be used to properly level the unit. The saw is shipped with an anti-rust protective coating

on machined metal surfaces. Surfaces should be cleaned with the appropriate solvent and then coated

with a light film of oil.

ELECTRICAL:

The machine is wired to be operated with an input voltage of 230, 3 phase, 60 htz

(+/- 10%) or with a Dake external step down transformer from 460v to 230v. If any adjustments or

changes are needed a qualified electrician should perform them. See detailed information as provided

in a circuit diagram #80587.

Manual V-16, V-24, VH-24, V-40 & VH-40 9 – Section I

WHEEL ALIGNMENT

V-16 & V / VH-24

Note: This alignment is factory set, but may need adjustment when replacing blade.

Two wheel machines have a bottom wheel that drives the saw blade and a top idle wheel that is

adjustable to facilitate blade tracking. The edges of the wheels are fitted with a composite material to

accommodate the tooth set.

The idle wheel may be adjusted by loosening the knurled locking collar and turning the black knob in

the center of the wheel. Turning the knob in a clockwise

manner runs the blade toward the back edge

of the band wheel. A counter clockwise

movement will move the blade toward the front edge of the

band wheel.

Correct tracking takes place when the blade runs approximately in the center of the wheel.

NOTE: The main casting with adjusting screws have been preset at the factory during assembly

utilizing special fixtures. No adjustment should be attempted.

V-40 / VH-40

Machines with two idle wheels in addition to the drive wheel possess tracking control on each wheel.

The top band wheel is set at the factory and no future adjustment should be necessary. *All

adjustments should be performed utilizing the third band wheel. If difficulty is encountered in tracking,

the top wheel may be reset as if the machine were to be used in the two wheel mode.

NOTE: With the V / VH-40 machines, it is possible to

have the blade appear to be tracking properly but in

actuality the two band wheels can be adjusted so they

form an intersecting planes, rather than a common plane

or parallel plane. This will result in excessive wear on

the crown on the band wheel by the blade teeth, and

severe cases, the composite material will shred or

actually come loose from the band wheel.

*If the blade does not track properly against the back up

guide bearing, there is a small amount of lateral

adjustment in the top wheel. (See figure 5) Loosen the

set screws and slide the yoke to make the blade line up

properly with the backup guide bearing.

BLADE INSTALLATION

Blade selection is based on the many factors and complexity of the work to be cut.

The blade placed on the band wheels with teeth facing toward the operator and down toward the top of

the worktable. Tension the blade to remove slack. Rotate the wheels by hand to ensure tracking is

correct, and blade will not “pop” off when machine is started. If tracking is incorrect, adjust before

starting machine.

4/29/03

Manual V-16, V-24, VH-24, V-40 & VH-40 10 – Section I

BLADE TENSIONING

The blade indicator is located inside the upper wheel compartment, on the lower left side of the idle

wheel. (See machine features graphic) The indicator has an arrow mounted on the horizontal plane,

with a corresponding scale for blade tensioning. The scale has two legends, one reads inches from 0 -

1”, the second reads mm 0 - 25 mm. This allows tensioning either standard or metric blade widths.

With out tension on the blade, the indicator should read zero. As tension is applied to the blade the

needle will move accordingly, and should be tightened until the correct blade width is indicated on this

gauge. Example: Installing a 1/2” blade on the machine, tighten the handwheel until the indicator’s

arrow is pointing to the 1/2” mark on the scale. Before starting the machine check the blades tracking

by hand as described in an earlier section.

This indicator has been calibrated at the factory. If recalibration is ever needed follow the steps below.

Using a blade tension gauge, (many times the

company that you purchase blades from can furnish

you with this gauge) tension the blade to the proper

PSI. The PSI will very from blade types (carbon, Bi-

metal) and blade widths. This information can be

obtained from your blade supplier. When proper

tension is achieved, loosen the setscrew in the collar

on the tensioning wheel shaft. (See figure 6) Adjust

this collar up or down on the shaft until the arrow is

pointing to the corresponding blade width. on the

indicator. Tighten setscrew.

Note: It is better to over tension the blade than to

run it under tensioned.

BLADE GUIDES

Your machine has come equipped with a set of interchangeable “V” type blade guides. A set of

guides consist of two each left hand and two each right hand guide inserts. The standard

guides furnished are 10 / 12 mm guides. Other sizes are optional, and can be purchased

separately, or as a five piece set. The five-piece set includes 3 / 4 mm (1/8 - 1/4”) 6 / 8 mm

(5/16 - 3/8”) 10 / 12 mm (standard set 1/2 - 5/8”) 16 / 20 mm (3/4”) and 25 / 32 mm (1”) The

blade width will dictate the size blade guide to be used.

Note: Never use blades larger than the rated capacity of the machine. Never use blades

narrower than guide insert. Damage will occur to guide insert and blade. Blade insert must

correspond with blade width.

4/29/03

Manual V-16, V-24, VH-24, V-40 & VH-40 11 – Section I

An analysis of the work to be performed should be made and the proper

blade selected. The blade should always be inspected before installing

on the machine. Things to look for should be the smoothness on the

sides and back edge of the weld, look for any missing teeth, or

impacted chips. The blade guides may now be selected and inserted

into both the upper and lower guide holders. Proper adjustment of these

guides takes place when they form a complete “V” shape (see graphic

below) and support the blade equally on each side. A couple of

thousands on each side of the blade will provide the running clearance

and support for contour sawing.

Note: Blade guides should be cleaned of chips each blade

change or more frequently if required.

BLADE GUIDES

The back end roller that supports the back of the blade on each guide holder contains a hardened cap

over a set of ball bearings. This should be checked periodically for free movement so it is allowed to

rotate freely as the back of the blade comes in contact with the face of this roller. Noticeable friction in

this assembly indicates it should be replaced. This can be done by removing the right hand guide

insert, moving the left hand guide up away from the bearing face. Loosen the setscrew on the bottom

of the guide holder and sliding the old bearing and shaft out and a new one in. Tighten the setscrew

and re-adjust the guides. See graphic below.

The “V” type solid blade guides and holder assemblies as furnished standard with the machine are

recommended for the majority of cutting applications. This is true for the cutting of materials at blade

speeds in the low range.

If the machine is operated in the high range, it should be operated with the high-speed roller guides,

supplied with this machine, installed.

NOTE: If machine is operated in excess of above, abnormal blade wear and breakage may

occur, due to the increased heat developed with the standard solid guides.

4/29/03

Manual V-16, V-24, VH-24, V-40 & VH-40 12 – Section I

HIGH SPEED ROLLER GUIDES

Applications and Advantages:

Friction and abrasive cutting, filing operations, aluminum and woodcutting.

These guides eliminate having to change inserts when changing to blades of different widths.

Requirements for Installation:

These roller guides must be installed using a new

1/2” blade width band for proper alignment.

The 1/2” band should be tracked within the approximate center line of the band wheels.

Note: Be certain band wheels are clean are free of any foreign material build up before

proceeding.

Tools / Hardware Required:

Drill - 7/16”

Drill and tap for ¼” 20 set screw

¼” 20 set screw 1/4 - 3/8” long

Upper Guide Installation:

1: Remove the existing guide holder assembly (part A)

via the 2 countersunk socket head cap screws located

on the backside of the moveable guide arm post. (Part

B) Store the original guide holder assembly for future

use. Remove the lower (red painted, part C) hold

down foot located at the bottom of the movable guide

arm post. (See graphic below)

2: With a 7/16” drill the bottom guide-mounting hole

out. Drill from the front of the guidepost, to a depth of

approx. 1”. The hole should be just deep enough to

stop short of breaking through the countersunk portion

of the hole.

3: Drill and tap a hole for a ¼” 20 set screw approx. ½ - ¾” back from the front edge of the guidepost.

This hole must be centered (intersect) with the 7/16” hole. As shown above.

4/29/03

Manual V-16, V-24, VH-24, V-40 & VH-40 13 – Section I

4: Insert the mounting stud (B) into the guide casting (A). Keep the stud

flush with the front of the casting. Keeping the mounting stud flat area

on the bottom, tighten securely the set screw (C) on the bottom of the

casting.

5: Insert this stud and guide assembly into the 7/16” hole in the guidepost. Make sure upper roller guide

is plumb with the guidepost. Lightly tighten set screw you installed in the guidepost.

Lower Guide Installation:

6: Remove lower blade guide. Replace this guide with the high

speed guide containing the

mounting bracket with slotted hole, reusing existing nuts /

bolts.

Position assembly upward along the slotted bracket, so that

the guide body casting has enough clearance to allow the

work table to be tilted for angle cutting. Tighten the socket

head cap screw or nut.

Note: Make certain that if a socket head cap screw is

used, it does not bottom out into the main saw casting

item 1. Shorten the cap screw if necessary

7: Alignment of Upper / Lower Guides:

With blade properly tensioned and tracked, position the

back-up roller by loosening the set

screw (A) on the front of the guide casting, and move the

knurled knob left to right until blade is in alignment with

the groove in the bearing. Rotate the knurled knob until

you have approx. 1/16” clearance from the back of the

blade to the front edge of the back-up roller. Tighten set

screw (A).

The two roller bearings below the back up bearing can

be adjusted in and out, left and right. Loosen the set screws that retain the bearing stems into the

casting. Using the single bearing assembly, position these bearings approx. 1/16” behind the deepest

gullet of the blade.

The single bearing assembly along with the adjustably of the upper guide roller will service blades from

¼” to ¾” The double roller set is used only when blade of ½” to 1” are used. Note: The adjustments

are the same for both single and double bearing assemblies.

Rotate eccentric bearing stems until both blade and the back up bearing groove are parallel with each

other. Set screws should be just snug up until actual alignment is confirmed.

4/29/03

Manual V-16, V-24, VH-24, V-40 & VH-40 14 – Section I

Repeat this process for the lower guide assembly.

Note: Upper guide stud may be adjusted in or out in the guide post to allow proper clearance for

blade, and for alignment with lower guide.

Align backup bearing as previously described for upper guide. Tighten both set screws when alignment

is confirmed.

Re-adjust side rollers. (Graphic in previous column) Set the side clearance distance between rollers

and saw blade, leaving about a .004 gap.

Note: If the adjustment setting for side clearance

between roller and blade is not enough, the side

rollers will cause the blade to miss-track or be

pushed outward from the guide rollers.

Note: If blade alignment from band wheel to

roller guides is necessary, do so by rotating

eccentric shafts on the roller guides. Then

lock them in place with the set screws.

After all adjustments have been made, tighten

all components tight.

BAND SPEED SELECTION

The saw blade is driven by a single speed transmission on the 16” machine and dual speed

transmissions on the 24” and 40” machines. The shifting lever on the larger models has three positions.

(Figure 1) The center being the neutral position, for set up. With the machine off, move the shift lever to

the left for low speed range (50-500 FPM) and to the right for the high speed range. (500-5000 FPM)

To shift the machine the shift lever handle must be pulled outward and then shifted left or right. (Figure

WARNING: NEVER SHIFT WHILE THE MOTOR IS RUNNING. THIS WILL CAUSE EXTENSIVE

DAMAGE TO THE DRIVE TRAIN.

4/29/03

Manual V-16, V-24, VH-24, V-40 & VH-40 15 – Section I

Note: Occasionally the drive wheel may have to

be jogged by hand to engage the transmission

lever.

The variable speed is achieved through the use of a

variable regulator. (Figure 3) This is turned clockwise

or counter clockwise to obtain an increase or

decrease in blade speed, in either range. Adjust until

desired speed is reached as read on the blade

speed gauge. (Figure 4)

WARNING: DO NOT ADJUST THE VARIABLE SPEED

CONTROL (FIGURE 3) SPEED UNLESS THE MACHINE IS IN

OPERATION! FAILURE TO DO SO WILL CAUSE SEALS TO

FAIL, AND RENDER THE UNIT INOPERABLE.

SAW BLADE SELECTION

There are numerous types of saw blades available depending upon the application. Tooth pitch, form,

tooth set, and blade composite make up all contribute to the desired cut. Blade speeds and feed are

also a factors. The complexity of the subject cannot be properly detailed in this manual, and it is

suggested that you contact your local blade supplier for more detailed information and

recommendations for the application.

Below is a chart that can be used as a guide line for blade selection and a percentage chart for

determining the speeds and feeds for material after determining the Rockwell hardness.

The chart below shows material shape and sizes of square solid, round solid, and tubing, channel, and

angle. The size range from 0” - 12” is diameter; the column under the shapes gives recommendation of

a vari-tooth blade. Example: 4” round solid, will require a 3/4 pitch blade.

Note: For structurals and tubing, determine the average width of cut.

Blades must be broke in properly, for longest life and best cut finish. Break in cutting should be

done at 1/3-1/2 normal cutting rate, for the 50-100 square inches.

NOTE: Below are the three most commonly used types of blades. The Bi-Metal blade is the most durable, for standard types of cutting

applications. The teeth are made of high speed steel and welded to a backing material. The cutting edge contains 8% cobolt with a Rc of 64

to 68. (These blades are more difficult to weld than standard carbon.) The carbon blade is the least expensive with reduced blade life. The

back of the blade is made of hardened material with a Rc of 31 to 37 and tooth hardness of 64 to 66. The carbide tipped blade has carbide

inserts welded to the blade teeth with a Ra rating of 92

SPEEDS AND FEEDS

As important as proper blade selection, is proper feeds and speeds for the different materials to be cut.

It is impossible to determine absolute rates for each material and machine, below is a chart that will

give you staring points for most applications; keeping in mind these are only approximations.

The left hand column, labeled Material tells you the family, the column Alloy lists the types that are

within that family of material. The top six columns give material dimensions. Below these column are

listed the recommended FPM and SIPM for that material type. Example: Carbon steel with a alloy make

up classified as 1030, with a diameter of 4” will be cut at 329 FPM and SIPM of 14, shown as fpm 329

sipm 14.
